Just a random question.

Back in the days of yore, How much AC was actually needed on those big fully rigged par can overloaded staged in the 1980's I'm guessing the equivalent of blocks worth of suburban houses. Or a shipyard...

Seems outrageous considering most bar rigs could be fed with 2 15A circus these days.
I had a friend who was backstage at a Van Halen concert at the Rainbow Theatre in London many, many years ago. Evidently they were carrying about 1000 par64 cans and there was no way the house power distro could handle that much power draw. So the only way to get access to almost 'limitless' power was to hook in to the incoming 3 phase mains (415V) before the house distro system. None of the stage or house crew were prepared to risk such a hook up but when substantial money was offered someone volunteered to do the deed and hooked power leads straight onto the incoming power cables. Result - show went ahead and the snow on the pavement (sidewalk) where the power cables came into the theatre miraculously melted.
